Definitions

  • the present invention relates to a supporting installation, and more specifically a supporting installation for supporting a number of turns extending helically one above the other in a belt pile and included in an at least partly self-supporting conveyor belt.
  • the supporting installation comprises an inner supporting structure which, together with an inner chain supported by and movable along the same, defines a first channel, in which one or more inner bearing elements are arranged, which inner chain is adapted to support a radially inner lateral edge of a lowermost turn of said belt pile, and an outer supporting structure which, together with an outer chain supported by and movable along the same, defines a second channel, in which one or more outer bearing elements are arranged, which outer chain is adapted to support a radially outer lateral edge of said lowermost turn of said belt pile, said inner and outer bearing elements being arranged for transfer of vertically downward forces from the respective chains to the associated supporting structure, and said inner bearing elements being arranged for transfer of radially inward forces from the inner chain to the inner supporting structure.
  • Supporting installations of the above type are used, for instance, in the food industry to support conveyor belts in compact air treatment plants, in which products arranged on the helically travelling conveyor belt are exposed to an airflow.
  • the airflow can be arranged, for instance, to freeze or heat the product.
  • Air treatment plants of this type thus comprise a conveyor belt and a supporting installation.
  • the conveyor belt is arranged in a helical path, below referred to as a belt pile, the supporting installation being arranged to support the lowermost turn of the belt pile. Relatively great, radially inward and vertically downward forces causing frictional forces are applied to the contact surfaces between the conveyor belt and the supporting installation.
  • US 4,899,871 discloses a supporting installation of the type described by way of introduction.
  • the inner and the outer chain are supported by an inner and an outer supporting structure, respectively, via bearing elements in the form of balls, which are arranged in a channel defined by the respective chains and the associated supporting structure and forming a ball race for the balls.
  • the balls act as a ball bearing between the conveyor belt and the supporting structures.
  • the inner chain is substantially identical to the outer chain.
  • a supporting installation is also known from SE 521, 775 , in which the bearing elements are in the form of rolls which are alternately arranged in a first and a second orientation.
  • friction may cause problems in these prior-art supporting installations. This is a drawback especially in connection with great belt pile weights, and it is particularly the engagement of the outer chain with said sliding strip which results in loss due to friction.
  • a first object of the present invention is to provide a supporting installation for supporting a number of turns extending helically one above the other in a belt pile and included in an at least partly self-supporting conveyor belt, in which supporting installation the loss due to friction is reduced.
  • a supporting installation for supporting a number of turns extending helically one above the other in a belt pile and included in an at least partly self-supporting conveyor belt, comprising an inner supporting structure which, together with an inner chain supported by and movable along the same, defines an inner channel, in which one or more inner bearing elements are arranged.
  • the inner chain is adapted to support a radially inner lateral edge of a lowermost turn of said belt pile.
  • the supporting installation further comprises an outer supporting structure which, together with an outer chain supported by and movable along the same, defines an outer channel, in which one or more outer bearing elements are arranged.
  • the outer chain is adapted to support a radially outer lateral edge of said lowermost turn of said belt pile.
  • each chain comprises abutment surfaces which form a radially outer side wall of the inner channel and the outer channel, respectively, and that said outer bearing elements are arranged for transfer of radially inward forces from the outer chain to the outer supporting structure.
  • each chain comprises abutment surfaces which form a radially outside side wall of the associated channel.
  • said outer bearing elements can also be used to transfer radially inward forces from the outer chain to the outer supporting structure. This eliminates the need for a sliding strip against which the outer chain abuts, thereby reducing the loss due to friction of the supporting installation.
  • the inventive supporting installation can manage higher belt pile weights and its chains are also subjected to reduced wear.
  • Each chain may comprise chain links which are interconnected by pull elements, which pull elements or chain links support said abutment surfaces.
  • Each chain link may comprise an upper and a lower link plate, which are arranged in parallel and interconnected in a spaced-apart manner by a spacer element arranged at a first lateral edge of the upper link plate, the upper link plate having an overhang projecting relative to the lower link plate, towards a second lateral edge opposite the first lateral edge, and the overhangs of the upper link plates in the chain links of each chain forming a top wall of the associated channel.
  • Each pull element may comprise a lower and an upper pull plate, two neighbouring chain links being hingedly connected by said pull elements.
  • the upper pull plates of the pull elements of the inner chain may support said abutment surfaces.
  • the lower pull plates of the pull elements of the outer chain may support said abutment surfaces.
  • Each chain may comprise a drive side with which a drive means is engageable to drive the chain, the drive side of the inner chain being oriented radially inwards and the drive side of the outer chain being oriented radially outwards.
  • the abutment surfaces of the inner chain can be arranged radially outside the drive side of the chain and the abutment surfaces of the outer chain can be arranged radially inside the drive side of the chain.
  • Said inner and outer bearing elements may comprise balls, rolls or sliding blocks.
  • bearing elements comprise rolls
  • these can be alternately arranged in a first and a second orientation, the rolls arranged in said first orientation being intended for transfer of forces from each chain to the respective supporting structures in a vertical downward direction, and the rolls arranged in said second orientation being intended for transfer of forces from each chain to the respective supporting structures in a radial inward direction.
  • the rolls intended for transfer of forces in the vertical downward direction can be positioned in such a manner relative to the associated lateral edge of the lowermost turn of the conveyor belt that the lateral edge is positioned between the ends of the rolls. This results in centring of the belt pile load relative to the bearing elements, which eliminates the tilting tendency of the chains.
  • the inner and the outer channel may be substantially square in cross-section. Such a cross-section is suited for bearing elements in the form of rolls or sliding blocks.
  • the inner and the outer channel may be substantially circular in cross-section, which is suited for bearing elements in the form of balls.
  • Fig. 1 is a schematic perspective view of a conveyor belt which along part of its extent travels in a helical path.
  • Fig. 2 is a schematic perspective view of an inner and an outer chain of an inventive supporting installation.
  • Fig. 3 is a cross-sectional view of an inventive supporting installation which supports a lower turn of a belt pile.
  • Fig. 4 is a perspective view, in partially exploded form, of a bearing element of an inventive supporting installation.
  • Fig. 5 is a top plan view of an outer chain of an inventive supporting installation.
  • Fig. 6 is a top plan view of an inner chain of an inventive supporting installation.
  • Fig. 7 is a cross-sectional view of an inventive supporting installation according to a second embodiment.
  • the present invention relates to a supporting installation for a conveyor belt 2 shown in Fig. 1, which along part of its extent comprises a number of turns extending helically one above the other in a belt pile 3.
  • the conveyor belt 2 is endless and extends from the upper end of the belt pile 3 in a path 4 outside the pile 3 to a lower end of the belt pile 3.
  • the conveyor belt 2 can be driven in any direction, that is the conveyor belt 2 can enter the belt pile 3 either at the upper end or at the lower end.
  • the supporting installation is arranged to support said belt pile 2 and comprises, as schematically shown in Fig. 2, an inner 5 and an outer 6 chain, which are adapted to be arranged under the lowermost turn of the belt pile 3 to support an inner and an outer lateral edge, respectively, of the conveyor belt 2.
  • the supporting installation may comprise a drive motor assembly 7 which engages the respective chains 5, 6 for driving the conveyor belt 2.
  • the supporting installation in combination with the conveyor belt is advantageously used in air treatment plants, such as a freezing plant.
  • the supporting installation and the belt pile are then arranged in an enclosing housing through which cold air flows.
  • the sequence of operations of a freezing plant can be, for instance, such that a food product is placed on the conveyor belt.
  • the product is then supplied to the housing through an inlet and frozen by the cold air while being conveyed in the helical path of the conveyor belt in the housing.
  • the food product exits the housing it is removed from the conveyor belt which via a return path is returned to the inlet of the housing.
  • the supporting installation is arranged to support the belt pile by supporting the lowermost turn.
  • the supporting installation 1 comprises to this end, in addition to said chains 5, 6, also an inner 8 and an outer 9 supporting structure, which is shown in Fig. 3, to which reference is now also made.
  • the supporting structures 8, 9 are each extended along an endless path.
  • the inner chain 5 is supported by and movable along the inner supporting structure 8 and the outer chain 6 is supported by and movable along the outer supporting structure 9.
  • the supporting structures 8, 9 are arranged to support the belt pile 3 via said chains 5, 6.
  • each supporting structure 8, 9 therefore comprises a conveyor belt supporting portion 10 and a return portion 11.
  • the conveyor belt supporting portion 10 of each supporting structure 8, 9 extends substantially along the lateral edge of the lowermost turn of the belt pile 3, which lateral edge each supporting structure 8, 9 is arranged to support via the associated chain 5, 6.
  • a drive motor assembly 7 is arranged for each chain 5, 6, each drive motor assembly 7 being arranged for driving engagement with the associated chain 5, 6 when this is moved along the associated return path 11.
  • Each supporting structure 8, 9 defines, together with the associated chain 5, 6, an inner 12 and an outer 13 channel, respectively.
  • the inner channel 12 holds inner bearing elements 14 and the outer channel 13 holds outer bearing elements 15.
  • each bearing element 14, 15 is an elongate structure comprising interconnected rolls 16a, 16b which are alternately arranged in a first 17a and a second 17b orientation.
  • Fig. 4 illustrates a partial portion of such a bearing element.
  • the bearing elements 14, 15 act to transfer vertically downward and radially inward forces, which the belt pile 3 exerts on the chains 5, 6 to the respective supporting structures 8, 9.
  • the rolls 16a arranged in said first orientation 17a can act to transfer vertically downward forces and thus have radially extended longitudinal axes 18, while the rolls 16b arranged in the second orientation 17b can act to transfer radially inward forces and thus have vertically extended longitudinal axes 19.
  • the cooperation between the chains 5, 6, the bearing elements 14, 15 and the supporting structures 8, 9 will be described in more detail below.
  • the supporting installation 1 can be arranged to support a wholly or partly self-supporting conveyor belt 1.
  • a self-supporting conveyor belt is meant that at least one lateral edge of a superjacent turn of the conveyor belt is piled along the distance it extends helically on a corresponding lateral edge of a subjacent turn of the conveyor belt.
  • the conveyor belt supporting portion 10 of each supporting structure 8, 9 has a pitch and thus takes the shape of a helical turn. Consequently, the belt pile 3 is formed when the opposite lateral edges of the conveyor belt 2 extend along the respective conveyor belt supporting portions 10 of the supporting structures 8, 9.
  • the conveyor belt supporting portions 10 are substantially circular, whereby the formed belt pile 3 takes on a circular cylindrical shape.
  • the conveyor belt supporting portions can have other shapes, for instance elliptic, whereby the formed belt pile takes on an elliptic cylindrical shape.
  • the pitch of the conveyor belt supporting portions 10 is such as to correspond to the height of the conveyor belt 2. This means that when the lower turn of the conveyor belt 2 has extended one turn along said conveyor belt supporting portions 10, this turn is piled on a new lowermost turn of the belt pile 3, provided that the conveyor belt 2 is driven in such a direction that it is supplied to the lower end of the belt pile 3.
  • both the inner 14 and the outer 15 bearing element act to transfer vertically downward and radially inward forces from the respective chains 5, 6 to the associated supporting structure 8, 9.
  • Each bearing element 14, 15 is, as mentioned above, arranged in a channel 12, 13 defined by the respective chains 5, 6 and the associated supporting structure 8, 9.
  • Each channel 12, 13 obtains a bottom wall 20 and a radially inner wall 21 from the supporting structure 8, 9 and a top wall 22 and a radially outer wall 23 from the chain 5, 6.
  • the bearing elements 14, 15 in the shown embodiment being given the shape of rolls 16a, 16b alternately arranged in said first 17a and second 17b orientation, the channels 12, 13 are square in cross-section.
  • each chain 5, 6 comprises a drive side 24, which is adapted to engage said drive motor assembly 7.
  • said drive side 24 is oriented radially inwards and, for the outer chain 6, said drive side 24 is oriented radially outwards.
  • the outer chain 6 comprises outer chain links 25 which are interconnected by outer pull elements 26.
  • Each outer chain link 25 comprises an upper 27 and a lower 28 link plate, which are arranged in parallel and interconnected in a spaced-apart manner by a spacer element 30 displaced towards a first lateral edge 29 of the chain 6.
  • the first lateral edge 29 is identical to the drive side 24 of the chain 6.
  • the spacer element 30 comprises two cylindrical bodies 31 which are arranged spaced from each other in the longitudinal direction of the chain 6. The bodies 31 define between them a space, in which teeth of a gear wheel of the drive motor assembly 7 can engage to drive the chain 6.
  • the upper link plate 27 has an overhang 32 projecting relative to the lower link plate 28, towards a second lateral edge 33 opposite the drive side 24.
  • the overhangs 32 of the chain links 25 form the top wall 22 of the channel 13 for the outer bearing element 15.
  • outer chain links 25 are interconnected by outer pull elements 26 which each comprise an upper 34 and a lower 35 pull plate which form a hinged connection between neighbouring chain links 25.
  • the lower pull plate 35 supports a vertically arranged abutment surface 36.
  • the abutment surfaces of the lower pull plates 35 form the radially outer wall 23 of the channel 13 for the outer bearing element 15.
  • the abutment surfaces 36 are thus arranged radially inside the drive side 24 of the chain 6.
  • the inner chain 5 comprises inner chain links 37 which are interconnected by inner pull elements 38.
  • Each inner chain link 37 comprises an upper 39 and a lower 40 link plate, which are arranged in parallel and connected in a spaced-apart manner by a spacer element 42 displaced towards a first lateral edge 41 of the chain 5.
  • the first lateral edge 21 is identical to the drive side 24 of the chain 5.
  • the spacer element 41 comprises two cylindrical bodies 43 which are spaced from each other in the longitudinal direction of the chain 5. The bodies 43 define between them a space, in which teeth of a gear wheel of the drive motor assembly 7 can engage to drive the chain 5.
  • the upper link plate 39 has an overhang 44 projecting relative to the lower link plate 40, towards a second lateral edge 45 opposite the drive side 24.
  • the overhangs 44 of the chain links 37 form said top wall 22 of the channel 12 for the inner bearing element 14.
  • inner chain links 37 are interconnected by inner pull elements 38, which each comprise an upper 46 and a lower 47 pull plate, which form a hinged connection between neighbouring chain links 37.
  • the upper pull plate 46 supports along said second lateral edge 45 a vertically arranged abutment surface 48.
  • the abutment surfaces 48 of the upper pull plates 46 form the radially outer wall 23 of the channel 12 for the inner bearing element 14.
  • the abutment surfaces 48 are thus arranged radially outside the drive side 24 of the chain 5.
  • both the inner 5 and the outer 6 chain are thus arranged so that the channel 12, 13 defined by the respective chains 5, 6 together with the associated supporting structure 8, 9 has a radially outer wall 23 which is possessed by the chain 5, 6.
  • a considerable reduction of the loss due to friction is provided in the supporting installation 1, which allows increased belt pile weights and also results in reduced wear on the supporting installation 1, above all on its outer chain 6.
  • both the inner and the outer bearing element 14, 15 consist in the shown embodiment of rolls 16a, 16b arranged in a first 17a and a second 17b orientation.
  • the channels 13, 14 have been given such a design that the rolls 16a arranged in said first orientation 17a, that is the rolls 16a which are adapted to transfer vertically downward forces, are positioned so that each lateral edge of the conveyor belt 2 is positioned between the ends of the rolls 16a. This ensures that the force exerted by the belt pile 3 on the chains 5, 6 does not strive to tilt the chains.
  • a bearing element from, on the one hand, rolls which are adapted to transfer vertically downward forces and, on the other, sliding blocks which are adapted to transfer radially inward forces.
  • the chains 5, 6 and the associated bearing structures 8, 9 have been adjusted so that the channels 12, 13 defined by them are substantially circular in cross-section.
  • the abutment surfaces of the outer chain have been described to be supported by the lower pull plates of the outer pull elements, and the abutment surfaces of the inner chain have been described to be supported by the upper pull plates of the inner pull elements. It will be appreciated that this is a conceivable embodiment of the present invention. It is thus possible, for instance, to let the abutment surfaces of the outer chain be supported by the lower link plates of the outer chain links. It would also be possible to let the abutment surfaces of the inner chain be supported by the upper link plates of the inner chain links.
